7. The communication gateway of claim 5, wherein the translation engine further comprises:

an IP engine operable to extract an originating address from the presence information signals; and

a HTTP engine operable to translate the presence information signals to SIP protocol signals.

8. The communication gateway of claim 1, wherein the presence information signals include presence information of a presence information provider.

9. The communication gateway of claim 8, wherein the presence information provider comprises:

a human user; and

a presence-enabled electronic device.

10. The communication gateway of claim 1, wherein the message bearer is further configured to receive presence signal information from the translation engine for transport to the wireless message center.

11. The communication gateway of claim 10, wherein the translation engine is further operable to receive SIP formatted signals from the IP network and translate the SIP formatted signals into signals capable of being formatted and transmitted by the message bearer box to the wireless message center.

12. The communication gateway of claim 10, wherein the translation engine is further operable to receive HTTP formatted signals from the IP network and translate the HTTP formatted signals into signals capable of being formatted and transmitted by the message bearer box to the wireless message center.

13. A method of communicating between a wireless packet-switched signaling network and an Internet Protocol (IP) network, comprising the steps of:
